I also tried the 3D image shooting and viewing. Although I never went crazy for stereo
views, this option works quite easy. You have to set the 3D mode, then take a picture of
your subject with the help of vertical guide lines on the screen, then move to your right
and take another picture with the help of a partial image in central area of the LCD, so
that both images will be centered each other and properly aligned. Then print the
resulting double picture in postcard size and view them through the special 3D viewer of
the Optio 230. At first youll have problems in seeing one single image, but then
youll succeed and youll see true 3D perspective. Nice, maybe once or twice a
year. Well, if you are a stereo fan, you probably wont pardon my low enthusiasm for
such feature, but the Optio 230 is your digital camera for sure.

Battery life
With the original lithium battery I took about 50 pictures in a couple
of days. Now the frame counter is beyond 60 and the original lithium battery is still
alive, but starts warning its no longer fully charged. I believe it can reach about
100 pictures before a replacement will be necessary, as opposed to 500 pictures as stated
in the instruction manual. Here an explanation about the battery is needed. Why do
manufacturers always give you false data about battery life and the number of pictures you
can take with it? What are those alien manufacturers test conditions extending so
much the duration of a camera battery to an extent youll see nowhere on planet
Earth?
I made some tests and discovered that if you shoot and shoot
continuously, youll probably get close to what manufacturers say about number of
shots allowed by a good fresh battery. The problem is that in real life youll switch
the camera on, frame your subject, change the lens focal length, and then sometimes even
decide not to take a picture at all. Also, often you have to check the menu settings. Then
youll switch the camera off, or maybe youll view some stored pictures, then
youll download them to your PC. Also, as you switch between shooting and replay
modes, the lens will automatically retract and extend a lot of times, not to speak if you
leave the camera on, ready for shooting for some time. Sooner or later (sooner than you
think!) the auto power off will switch the camera off for power saving and protecting the
lens, but each operation will need some extra power. At the end, most of power will be
gone for auxiliary operation, not for actual picture taking, and all of your efforts for
not using the LCD more than necessary, will bring little results. My advice? Find the best
way for having plenty of power. Be sure to carry with you more than one set of good
rechargeable batteries (NiMH for the Optio 230, Li-Ion for the 330/430) and never forget
to recharge all of them as soon as possible. Thats the only way for not being so
often short of power, with a camera only good as a paperweight.
Conclusions
Well, I have to admit that the Optio 230 seriously challenges my Optio
330, especially with its quick response when depressing the release button, its lens
quality and improved macro capability.
Its larger size compared to the 330/430 is not so large at all, and it
wont be enough of a reason for your choice, while its lower price can make the
difference. The foldout screen and the 3D mode are not essential to me, while Id
miss the manual exposure setting.
The plastic body can be less appealing, but not so much. Somebody could
also find it a plus, since it makes the Optio 230 less a jewel to worry about when
carrying it with you all the time. On the other hand, the Optio 330/430 are true gems that
can fascinate you, and the new 330RS/430RS are even more appealing, if possible (and they
even feature quick response shutter release!).
All considered, I wont switch from my Optio 330 to the new 230, but I can
recommend it to anybody wishing a good digital camera well under $500.
